experIence effIcIency farBeyondrequIreMenTs The renowned CrE pump has been upgraded with the latest motor technology to offer impressive energyefficiencythatexceedstheIE4levels,evenincludingtheenergyconsumptionofthevariable frequency drive. When you choose the optimised CrE pump, you will not only be rewarded with superior reliability and impeccable performance. As part of the grundfos isoLuTIons programme, the pump also represents the ultimate in intelligent control and energy efficiency. The new MgE motor goes far beyond what regulations require in terms of energy efficiency just as the advanced built-in control system makes it possible to enable application-related functions to optimise system performance. Also, the CrE pump is now suitable for installation in more applications due to increased permissible ambient temperature and lower noise level.
